Oh, you mean having to setup all the needed Angular module imports and declarations? Are you aware of SCAMs?

One advantage is that you can often just import a component's SCAM to test it. It's so unexpectedly easy that Spectator had to put in a special option to undo some of its normal affordances to make component tests easier to set up.

That's great. It's annoying to have to put everything in the TestBed module.

Anything in Angular is more complex than the other frameworks.
